IMPROVEMENT IN CARBURETING ATTACHMENTS FOR GAS-EURNERS.

Specification forming part of Letters Patent N0. 131,210, datedSeptember 10, 1872.

SPECIFICATION.

To whom it may concern:

Be it known that I, JOHN H. BUTLER, J r., of Park Ridge, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Garbureting Attachments for Gas-Burners, of which thefollowing is a full, clear, and exact description, which will in g gasat or near the burner; and it consists in certain novel features in theconstruction and arrangement of a float device, suspendin g a fibrous orabsorbent material at an unvarying distance in and above the liquid asthe latter varies in depth, in combination with a reservoir providedwith an induction-pipe constructed to fit upon the burner and supportthe reservoir, and with a filling-tube and eduction-pipe, the latter ofwhich. is provided with a burner or, tip, all of which will be hereaftermore fully described.

In the drawing, A represents the reservoir. B is a tube extending intothe reservoir to, or nearly to, the top thereof, and open at both ends,the lower end of which is rigidly attached to the reservoir so as toprevent leakage; it is also of such size and form as to sit firmly andclosely over a gas-tip or, other gas-induction tube to which it may beapplied, as shown at G, which represents a gas-tip. D is a float of corkor other suitable material. D is a cap firmly attached to the float D byscrew attachment or otherwise. d d are perforations in the top of thecap D, and d is a fibrous material drawn through the perforations :1 d,and depending a short way below the lower surface of the float D. e eare perforations in the vertical part of the cap D, and communicatingwith the reservoir A. D

is a tube, closed at the top and passing through the cap D, andextending a short way below the lower surface of the float D. ff areperforations in the tube D, and communicating with the chamber formed bythe cap D. E is the filling or induction tube for filling the reservoirwith liquid, and E is a cap attached to the top of the tube E by screwattachment or by a ground joint so as to be air-tight. F is aneduction-pipe, and F is a gas-tip mounted thereon. The float device D DD is arranged about the tube B in the manner shown,

and so as to rise and fall in the tube E as the reservoir is filled oremptied.

The reservoir is filled by removing the cap E and pouring the liquidthrough the tube E. The tube D, by being closed at the top, prevents theliquid from entering the tube B, and the latter, by extending to ornearly to the top of this reservoir, admits of the reservoir beingfilled, and prevents the float device from floating away from the saidtube 13.

It is obvious from the foregoing description that the capillaryattraction will be through a medium, d, suspended at an unvaryingdistance in and above the liquid within the reservoir. For the purposeof carbureting the reservoir is filled with hydrocarbon liquid. When thegas is turned on it passes from the tip 0 through the tube B, dives overthe top of the latter, passes down through the tube D, through theperforations ff into the chamber of the cap D, through the perforationse 0 into the reservoir, and from thence, through the pipe F and tipthereon, to the flame. The

process of carburetingis facilitated by reason of the capillaryattraction of the material 01, which, being constantly saturated,increases the exposed surface of the hydrocarbon fluid at a point wherethe gas from the tip 0 comes in contact with it. The tube D, byextending below the lower surface of the float D, prevents a suction atthat point, which the passage of the gas through the carbureter wouldotherwise tend to create. The tube E, besides furnishing a convenientmeans of filling the reservoir, serves also to protect the float device.By removing the flame from the reservoir bymeans of the pipe F thedanger of overheating the contents of reservoir is prevented, and anopportunity is provided for attaching a cook or shut-off between thereservoir and the flame, if such attachment is deemed desirable.

I I am aware that carbureters have heretofore been made with a float,and therefore I do not claim such broadly; but,

Having described my invention, what I claim is- A carbureting attachmentfor a gas-burner, consisting of the reservolr A havlng the float D, withits cap D attached to the perforated tube D, arranged therein as setforth, the whole constituting a new article of manufacture, forattaching to ordinary gas-burners, as described.
